So far I love this bag. Super comfy and roomy. I've had other bags and just felt too constricted in them, the Xenon gives me plenty of space to move around and get comfortable, but still packs small and is very lightweight. I use this bag on a regular basis and have yet to have any complaints. I use it for backpacking and it's great

This bag was EN-tested to a rating of +19 degrees F. While I've never been to Kilimanjaro, a quick Google search implies that summit temps range from +20F to -20F and are very difficult to predict due to the mountain's prominence. While November IS the beginning of the warm season in that part of the world, it seems to me that you'd be taking an unnecessary risk by bringing a bag that would only be suitable for the best-case scenario. I'd look at one of the +0F bags (Ouray, Gamma, Lithium) or perhaps even the -20F Col Membrain,
